Heir we go again! Broody Wills and Kate want to try for baby number two

NUMBER TWO: William and Kate want Prince George to have a brother or sister soon [PA]

The Duke and Duchess of Cambridge are desperate to give Prince George a little brother or sister, a close pal revealed.

Prince William, 31, has even quipped he might “do a Beckham” and name the tot after the place where he or she is conceived.

“It could mean they’ll have a Princess Sydney!” the old friend laughed.

The source added: “They have made no secret of the fact they’d like three children and don’t see any point in waiting.

“Kate’s just turned 32 and wants all her babies over and done with before she is 35.

“Their trip Down Under is going to be a bit of a second honeymoon for them – they will have lots of quality time together.”

The royal couple even have another nursery ready next to seven-month-old George’s at Kensington Palace. And they have just hired a full-time nanny to help Kate balance the demands of motherhood and her royal duties.

The pal added: “I think they’d both quite like a girl – they’re keen on the name Alexa. They had been talking about trying at the beginning of the New Year, but decided to put it off until they go to Oz.

“They didn’t want to risk Kate getting morning sickness while she was away.”
